MILK-CAN.

Specification forming part of Letters Patent No. 52,695, dated February20, 1866.

To all whom it may concern:

Be it known that 1, JOHN Q. DAVIS, of Salem, in the county of Salem andState of New Jersey, have invented a new and useful Improvement inPortable Milk-Cans; and I do hereby declare that the following is a fulland exact description of the same, reference being had to theaccompanying drawings, making a part of this specification, in which-Figure 1 is a central vertical section of a portable milk-can having myimprovement applied thereto; Fig. 2, a horizontal section 011 the dottedline 00 of Fig. l; and Fig. 3, a like section on the dotted line y ofthe same figure.

Like letters of reference indicate the same parts when in the differentfigures.

The milk-cans now used for daily transporting fresh milk from thecountry to the cities are simply cylindrical tin vessels provided eachwith a wide mouth and closely-fitting re movable stopper. The milk,sometimes warm from the animal, is poured into the cans, and

transported, generally by rail cars, to the cities; but in summerweather it often becomes sour before it can be distributed to theconsumers; and to obviate this objectionable result, or to preserve themilk in its original sweet condition while in the cans is the object ofmy invention.

It consists, substantially as hereinafter described, in applying to theinterior of a portable milk-can a readily-iemovable vessel provided witha closely-fitting stopper for the reception and retention ot'asuflicient quantity of ice to keep the milk cool and sweet during thetime required for its transportation and distribution in warm weather,by means of a fixed flange in the bottom of the can and an annular bandfixed concentrically in the mouth of the same, the removable ice-vesselhaving suitable catches applied whereby it can be secured in or releasedfrom the milk-can with facility.

In the drawings, AB is the milk-can, and O D the removable vessel forreceiving and retaining the ice.

The milk-can A B is constructed of sheet metal in the usual well-knownform and manner, with the addition of an annular flange, E, which issoldered fast in the middle of the inner side of the bottom of the can,(see Fig. 1,) and of a band, F, which is rigidly supportedconcentrically in the mouth of the can A B by means of four (more orless) intervening arms, f f soldered fast to both can and band. (SeeFigs. '1 and 2.)

The ice-vessel O I) is cylindrical, of sufficient length to bring itsupper end about on a level with the lower end of the mouth of the can AB, and of a diameter about half that of the mouth of the can. It istitted with aclose stopper, and its lower end fits freely within theannular flange E when the said vessel O D is adjusted in the can A B.(See Fig.1.) Its upper end is supported and the whole vessel retainedsteadily in the can A B by means of two catch-springs, g g, which arefastened, respectively, to opposite sides of the vessel 0 D, and so bentas to form a shoulder on each which Will readily catch under the band Fwhen the lower end of the sa d vessel 0 D is inserted in the annularflange E of the can A B, the band F being made of a diametersufficiently large for the purpose.

It will be readily seen that the ice-vessel O D can be convenientlyintroduced into and withdrawn from the can A B at the pleasure of theinilkman, and that when introduced it will be retained steadily in itsproper posit-ion during the necessary transportation; and it will alsobe readily seen that when the said "essel O D is supplied with ice andinserted in the can A B, as described, it will necessarily keep thesurrounding milk in the required cool condition to preserve it in itsoriginal sweet state during its transportation and distribution, thequantity of ice being proportioned to the time.

The device is simple of construction, and can be readily applied to anyof the milk-cans in use at a small cost.

What I claim as new, and desire to secure by Letters Patent, is-

The flange E, in the bottom of the can A B, and the annular band F, inthe mouth of the same, when they are used in combination with aremovable ice vessel, 0 D, provided with the catch -springs g g, ortheir equivalents, the whole operating together substantially as and forthe purpose described.
